Need Help With User-Customized Post Feed In Profile…

I’ve been looking all over for tips on how to accomplish this and I’m either illiterate with coding, or overlooked it. Thanks in advance for any assistance.

I’m looking to have a feature on my site where registered users can create a customized/filtered post feed based off of tags only. So when a user has an account, they can choose from a list of tags to follow and each post from their selected tags would display in a tab on their profile.

The best example I can think of is the ‘Team Stream’ feature on Bleacherreport.com; they allow members to search and select their favorite teams, then every new post on that team would be fed into their profile.

I don’t know much about custom post types, hooks, queries, etc.; I was hoping someone could point me in the right direction : )
